Specification of Letters Patent No. 681, dated April 7, 1838; 
Antedated October 7, 1837.

To all whom it may concern:

Be it known that I, Reuben Daniels, of Woodstock, in the county 
of Windsor and State of Vermont, have invented a new and useful 
Improvement in the Construction of Crosscut Eclipse 
Shearing-Machines for Shearing Woolen and other Cloths from List 
to List, and that the following is a full and exact description 
of the construction and operation of said machine as improved: by 
me, viz:

Let there be constructed on a suitable platform or floor a 
railway of wood or other material having on the top a metallic 
wire smoothly finished two or more inches above the platform or 
floor; the length of the rails and their distance asunder being 
adjusted to the width of the cloth to be sheared, and to the 
length of the shear. The design and use of this railway is to 
receive and guide the cloth carriage under the shear in the 
process of shearing, and also the form and attachment for the 
cast iron spectacle frame, so called, from its resemblance to 
spectacle bows. This attachment must be on the outer side of the 
rails, so as to permit the cloth carriage to pass on the rails 
within the cast iron spectacle frame. The cast iron spectacle 
frame is a massy casting consisting of one entire piece, the 
object of which is not only to form an unyielding stationary 
support to the rest underneath the shear frame but also to give 
attachment to the iron shear frame in which the revolver runs, 
and to which the ledger blade is attached. This rest is attached 
to the spectacle frame by means of set screws in such manner that 
either end of the rest may be raised or depressed or moved 
backward or forward so as to be exactly adjusted to the revolving 
and ledger blades while shearing. The upright spectacle frame 
gives attachment to all the stationary parts of the machine above 
the rails. It is constructed with two upright posts of the height 
of the cloth carriage. These posts are connected by two circular 
parts adapted to receive the cloth rolls, having the cloth wound 
around them. These cloth rolls or beams are a portion of the 
cloth carriage and as long as the width of the cloth to be 
sheared. The form of the spectacle frame is shown in drawings 
Figure 5 and marked N, N. Immediately above the two circular 
parts is placed the cloth rest, which is fastened to them by 
means of set screws already described. The top of this rest is to 
be brought to a degree of sharpness resembling No. 18 wire so as 
to present but a very small portion of the cloth to the action of 
the shear in each successive portion of time; and yet not so 
sharp as to endanger the rending of the cloth. The ends of the 
rest are to be smoothly rounded to permit the cloth to pass 
without damage. The shear frame is placed over the rest in such 
position that the edge of the ledger blade falls immediately in 
contact of the rear of the upper edge of the rest, while the 
center of the revolving blade lies immediately over the wire edge 
of the rest. Within a small distance of this edge two ledges 
project down upon the cloth, the one before and the other behind 
the shear, the object of which is to depress the cloth on each 
side of the wire edge of the rest, and permit the nap to rise 
above the thread to meet the action of the shear. These ledges or 
projections are shown, Fig. 3 and marked L, L. The shear frame is 
of one solid casting and gives attachment to the revolving and 
ledger blades, the oiler stand and oiler, the gage screws, and 
dial, and dial dog with the ledges above described, and marked L, 
L. The ledger blade is a separate piece, and is attached to the 
shear frame at each end, and in the center by set screws, so that 
it can be raised or depressed at pleasure. The object of the set 
screws in the center of the ledger blade is to attach the ledger 
blade to a strong and unyielding portion of the shear frame to 
support it in position without trembling. This strong unyielding 
portion of the shear frame is marked in the drawings by Q, and 
the set screws are shown by lip D. A stand is attached to the 
spectacle frame to support the bearings of the shear frame which 
is so constructed as either to lie down close to the cloth while 
shearing or to be raised up when the shear has reached the list 
and the cloth frame requires to be drawn back preparatory to 
shearing another portion of the cloth. This stand is marked B, in 
drawing Fig. 2. The strong unyielding portion of the shear frame 
is shown in drawing Fig. 1, and marked Q as above described. Two 
scroll stands are attached to the spectacle frame and are shown 
in the drawing Fig. 3 and marked S, S. Into these scroll stands 
are introduced the bearings of the balance shaft small friction 
roller, end of shaft in contact with cam. K dog shaft shown in 
Fig. 3. L pinion wheel playing into gear. M, M, &c., frame of 
cloth carriage. N, Not, &c., spectacle frame. β€” the hand lever. β€” 
the balance lever. I, shaft connecting trucks. K large pulley on 
dog shaft. L strap of iron connecting lever handle D with cam H. 
e, e, cords or fastenings stretcher to connect the hand roll to 
the L, L, two ledges to depress the cloth over the cloth rest. O, 
balance weights. P rack into which pinion wheel plays. Q 
unyielding part of shear frame. E, E, rail

β€” ways. S large pulley on main shaft carrying revolving blades. T 
small cam to move oiler Fig. 2. U crank or cloth roll Figs. 2 and 
3. V rest Figs. 3 and 5. W floor on which machine stands. X lever 
to move oiler. Y belt driving revolving blades. X oiler. Z weight 
on dog shaft, a, oiler stand.

b, stands for gudgeons for shear frame.

c, c, braces from rail ways to spectacle frame. d, set screws to 
regulate shear frame. P latch holding down lever handle D while 
shearing. T pulley moving the cam to turn the oiler. I, I, box 
holding bearings of revolving blades. f thumb screws to move the 
latch. S, S, scroll stands, p, p, main pulley shaft.

In the specification thus presented, it is not designed to 
specify every minute portion of the machine, and those portions 
not specified are common to this and other machines of a similar 
kind in use.

All I claim as my invention isβ€”

The above combination and arrangement of any two or more of the 
following particulars of the above described cross cut eclipse 
shearing machine, when combined with the cloth carriage; first, I 
claim the cast iron receptacle frame; secondly, the cloth rest 
with wire edge; thirdly, the dial plate set screws to regulate 
the length of nap; fourthly, the cam to lift pinion wheel out of 
rack, and fifthly, the ledge to depress the cloth in front of the 
shear. But I do not claim as my invention any one of the above 
described parts, or a combination of them, independently of their 
combination with the cloth carriage, nor do I claim the cloth 
carriage as my invention.
